The spring fixing seat 63 is annularly arranged around the first fixed platform 62, and a spring 631 is attached to the second fixed platform 64 connected to the spring fixing seat 63. The main shaft 65 is positioned between the first fixed platform 62 and the first fixed platform 62. The bearing 66 surrounds the main shaft 65 inside the connecting cylinder 5. The fixing mechanism 67 is located inside the locking mechanism 4 and the connecting cylinder 5. The screwdriver mechanism 68 is located inside the fixing mechanism 67. The main shaft 65, in conjunction with the fixing mechanism 67, rotates the screwdriver mechanism 68.

[0027] In detail, a connecting plate 651 is provided on the top of the main shaft 65, a connecting plate 652 is provided above the connecting plate 651, a bearing groove 653 is provided between the connecting plate 651 and the connecting plate 652, and a strong positive magnetic plate 654 is provided on the top of the connecting plate 652.

[0028] The main shaft 65 has a cylindrical structure. Both the connecting plate 651 and the connecting plate 652 have cylindrical structures and are the same size. The central part between the connecting plate 651 and the connecting plate 652 is the main shaft 65. The connecting plate 651, the connecting plate 652 and the main shaft 65 are integrally formed. The powerful positive magnetic plate 654 has a circular structure and the circumference of the powerful positive magnetic plate 654 is smaller than the circumference of the connecting plate 652.

[0029] The fixing mechanism 67 includes a fixing plate 671, a fixing post 672, a plug groove 673, a convex ring 674, a locking ring 675, and several limiting strips 676. The fixing plate 671 is located on the top of the bearing 66, the fixing post 672 is located on the top of the fixing plate 671, the plug groove 673 is located inside the fixing post 672 and opens upward, the convex ring 674 is located at the bottom of the plug groove 673, the locking ring 675 is located inside the convex ring 674, and several limiting strips 676 are arranged in a fan-shaped structure around the inside of the plug groove 673.

[0030] The top of the spindle 65 passes upward through the fixing plate 671, and the connecting plate 651 and connecting plate 652 are all located at the bottom of the insertion slot 673. The fixing plate 671, fixing post 672, and spindle 65 are integrally formed. The locking ring 675 is located on the bearing groove 653, and the bottom of the limiting strip 676 has an inclined structure. The integrally formed structure of the fixing plate 671, fixing post 672, and spindle 65 facilitates rotation and provides higher stability during operation.

The screwdriver head 681 is cylindrical and located inside the insertion slot 673. The inserts 682 are arranged in a fan-shaped pattern around the bottom of the screwdriver head 681. The inserts 682 and the limiting strip 676 have a complementary structure, fitting together perfectly and forming a ring structure. The powerful negative magnetic plate 683 is circular and located at the bottom of the screwdriver head 681. The circumference of the powerful negative magnetic plate 683 is smaller than the circumference of the screwdriver head 681. The screwdriver hole 684 is located at the top of the screwdriver head 681. The attraction between the powerful negative magnetic plate 683 and the powerful positive magnetic plate 684 further strengthens the fixation of the screwdriver head and makes disassembly and assembly more convenient.

[0032] Working principle: When installing the screwdriver bit 681, hold the upper part of the bit 681 and insert it through the insert 682 into the gap between each pair of adjacent limiting strips 676 until the strong negative magnetic plate 683 is attracted to the strong positive magnetic plate 654. Installation is then complete. During operation, the spindle 65 rotates along with the fixing mechanism 67, causing the screwdriver bit 681 to rotate. During rotation, the tight fit between the insert 682 and the limiting strips 676 ensures the stability of the screwdriver bit 681, and the strong attraction of the positive and negative magnetic plates prevents it from falling off during rotation. Disassembling the screwdriver bit 681 is quick and easy; simply apply a little force to pull it out.
